Hey Rusty, the diff highest temp was 170F after Autocross lap, but it got to 230F after high-way driving for 1 hour (with 60-70F weather). I called MA-Motorspots john referred me to Brian who said that those numbers are not bad and I might not need a cooler. Thoughts?

If you are using a temp gun. You are not getting a true lube temp. You could tack on another 10 degrees maybe more inside the diff.

What you got for doing a auto-x isn't bad. Street driving is getting up there. If you had a diff temp gauge. You would have a better idea of what's going on.

What gets me. Even the stock diff temps get up there close to cooking the lube.
